Comparison of Intraocular Lens Fixation Techniques Performed During Penetrating Keratoplasty

Abstract

We reviewed the charts of 41 patients who had undergone penetrating keratoplasty, anterior vitrectomy, and placement or exchange of an intraocular lens during a two-year period with a median follow-up time of 15 months (range, five to 26 months). The median preoperative visual acuity was 20/400 (range, 20/40 to hand motions). The median postoperative visual acuity was 20/70 (range, 20/25 to hand motions). Of 41 corneal grafts, 38 (93%) remained clear. New intraocular lenses were inserted by anterior chamber, iris, or transscleral fixation. The median visual acuity was 20/70 for the anterior chamber lens group, 20/100 for the iris fixation group, and 20/70 for the transscleral fixation group. Analysis of variance demonstrated no significant difference by type of fixation in postoperative visual acuity, central corneal thickness, and intraocular pressure.
